              [<EM>terminal-type</EM> ... ]


</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
       <STRONG>infocmp</STRONG>  reports  a  human-readable  terminal  type  description from a
       compiled entry in the <EM>terminfo</EM> database  in  a  variety  of  selectable
       formats,  compares such entries to each other, and rewrites an entry to
       replace  "<STRONG>use</STRONG>"  expressions  with  the  content  of  other  entries  by
       reference.   A  <EM>terminfo</EM>  <EM>entry</EM>  entry  comprises a list of one or more
       terminal type identifiers, a human-readable description of the terminal
       type,  and  a  list  of  terminal  <EM>capabilities</EM>  that  characterize its
       programming interface.  In all  cases,  the  program  reports  Boolean-
       valued  capabilities  first, followed by numeric ones, and then string-
       valued capabilities.


</PRE><H3><a name="h3-Default-Options">Default Options</a></H3><PRE>
       If  no  options  are  specified  and  zero  or  one  <EM>terminal-types</EM>  is
       specified,  <STRONG>infocmp</STRONG>  assumes  the  <STRONG>-I</STRONG>  option.   If  more  than  one is
       specified, the program assumes the <STRONG>-d</STRONG> option.


</PRE><H3><a name="h3-Source-Listing-Options_I_L_C_r_">Source Listing Options [-I] [-L] [-C] [-r]</a></H3><PRE>
       The <STRONG>-I</STRONG>, <STRONG>-L</STRONG>, and <STRONG>-C</STRONG> options will  produce  a  source  listing  for  each
       terminal named.

                   <STRONG>-I</STRONG>   use <EM>terminfo</EM> capability codes
                   <STRONG>-L</STRONG>   use "long" capability names
                   <STRONG>-C</STRONG>   use <EM>termcap</EM> capability codes
                   <STRONG>-r</STRONG>   with <STRONG>-C</STRONG>, include nonstandard capabilities
                   <STRONG>-K</STRONG>   with <STRONG>-C</STRONG>, improve BSD compatibility

       If  no  <EM>terminal-types</EM> are given, the environment variable <EM>TERM</EM> will be
       used for the terminal name.

       The source produced by the <STRONG>-C</STRONG> option may be used directly as a  <STRONG>termcap</STRONG>
       entry,  but not all parameterized strings can be changed to the <STRONG>termcap</STRONG>
       format.  <STRONG>infocmp</STRONG> will attempt to  convert  most  of  the  parameterized
       information,  and  anything not converted will be plainly marked in the
       output and commented out.  These should be edited by hand.

       For best results when converting to <STRONG>termcap</STRONG> format, you should use both
       <STRONG>-C</STRONG>  and  <STRONG>-r</STRONG>.   Normally a termcap description is limited to 1023 bytes.
       <STRONG>infocmp</STRONG> trims away less essential parts to make it  fit.   If  you  are
       converting to one of the (rare) termcap implementations which accept an
       unlimited size of termcap, you may want to add  the  <STRONG>-T</STRONG>  option.   More
       often  however,  you  must  help  the  termcap implementation, and trim
       excess whitespace (use the <STRONG>-0</STRONG> option for that).

       All padding information for strings  will  be  collected  together  and
       placed  at  the  beginning  of  the  string  where  <STRONG>termcap</STRONG> expects it.
       Mandatory padding (padding information with a trailing "/") will become
       optional.

       All  <STRONG>termcap</STRONG>  variables  no longer supported by <STRONG>terminfo</STRONG>, but which are
       derivable from other <STRONG>terminfo</STRONG>  variables,  will  be  output.   Not  all
       <STRONG>terminfo</STRONG>  capabilities  will  be translated; only those variables which
       were part of <STRONG>termcap</STRONG> will normally be output.  Specifying the <STRONG>-r</STRONG> option
       will  take off this restriction, allowing all capabilities to be output
       in <EM>termcap</EM> form.  Normally you would use both the <STRONG>-C</STRONG>  and  <STRONG>-r</STRONG>  options.
       The  actual  format  used  incorporates  some  improvements for escaped
       characters  from  terminfo  format.   For  a  stricter   BSD-compatible
       translation, use the <STRONG>-K</STRONG> option rather than <STRONG>-C</STRONG>.

       Note  that  because  padding  is  collected  to  the  beginning  of the
       capability, not all capabilities are output.  Mandatory padding is  not
       supported.   Because  <STRONG>termcap</STRONG>  strings  are  not as flexible, it is not
       always possible  to  convert  a  <STRONG>terminfo</STRONG>  string  capability  into  an
       equivalent <STRONG>termcap</STRONG> format.  A subsequent conversion of the <STRONG>termcap</STRONG> file
       back into <STRONG>terminfo</STRONG> format will not necessarily reproduce  the  original
       <STRONG>terminfo</STRONG> source.

       Some  common  <STRONG>terminfo</STRONG>  parameter sequences, their <STRONG>termcap</STRONG> equivalents,
       and some terminal types which commonly have such sequences, are:

                 <STRONG><EM>terminfo</EM></STRONG>                   <STRONG><EM>termcap</EM></STRONG>   Terminal Types

</PRE><H3><a name="h3-Entry-Comparison-Options_d_c_n_">Entry Comparison Options [-d] [-c] [-n]</a></H3><PRE>
       Given <STRONG>-c</STRONG>, <STRONG>-d</STRONG>, or <STRONG>-n</STRONG>, <STRONG>infocmp</STRONG> compares the <EM>terminfo</EM> description  of  the
       first  specified  <EM>terminal-type</EM>  with  those  of each of the subsequent
       operands.  If fewer <EM>terminal-types</EM> than required are specified, <STRONG>infocmp</STRONG>
       uses the environment variable <EM>TERM</EM> in their place.

       If  a  capability  is  defined  for  only  one terminal type, the value
       reported depends on the capability's type:

       <STRONG>o</STRONG>   <STRONG>F</STRONG> for missing Boolean variables

       <STRONG>o</STRONG>   <STRONG>NULL</STRONG> for missing integer or string variables

       The <STRONG>-c</STRONG> and <STRONG>-d</STRONG> options  report  string  capability  values  between  "'"
       characters.   Use  the  <STRONG>-q</STRONG>  option  to  distinguish <EM>absent</EM> and <EM>canceled</EM>
       capabilities; see <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>.

       The comparison option selects the form of report.

       <STRONG>-d</STRONG>   lists each capability that  <EM>differs</EM>  between  two  entries.   Each
            capability  name is followed by ":" and comma-separated capability
            values, then a period.

       <STRONG>-c</STRONG>   lists each capability that two entries have  in  <EM>common</EM>.   <STRONG>infocmp</STRONG>
            ignores  capabilities  missing from either entry.  Each capability
            name is followed by "=", a space, and the capability value, then a
            period.

            If  the  <STRONG>-u</STRONG>  option  is  further  specified,  <STRONG>infocmp</STRONG> rewrites the
            description of the first type employing "use=" syntax to  use  the
            second as a building block.

       <STRONG>-n</STRONG>   lists  capabilities  that  are in <EM>none</EM> of the given entries.  Each
            capability name is preceded by "!"  and followed by a period.

            Normally only conventional capabilities are  shown.   Use  the  <STRONG>-x</STRONG>
            option  to add BSD-compatibility capabilities (names prefixed with
            "OT").


</PRE><H3><a name="h3-Use_Option_u_">Use= Option [-u]</a></H3><PRE>
       The <STRONG>-u</STRONG> option produces a  <STRONG>terminfo</STRONG>  source  description  of  the  first
       terminal <EM>terminal-type</EM> which is relative to the sum of the descriptions
       given by the entries for the other <EM>terminal-types</EM>.   It  does  this  by
       analyzing  the  differences  between  the  first <EM>terminal-types</EM> and the
       other <EM>terminal-types</EM> and producing a description with <STRONG>use=</STRONG>  fields  for
       the  other  terminals.   In  this  manner,  it  is possible to retrofit
       generic terminfo entries into a terminal's  description.   Or,  if  two
       similar  terminals  exist,  but  were  coded  at  different times or by
       different people so that each description is a full description,  using
       <STRONG>infocmp</STRONG>  will  show  what  can  be done to change one description to be
       relative to the other.

       A capability will be printed with an at-sign (@) if it no longer exists
       in  the first <EM>terminal-type</EM>, but one of the other <EM>terminal-type</EM> entries
       contains a value for it.  A capability's value will be printed  if  the
       value  in  the  first  <EM>terminal-type</EM>  is  not found in any of the other
       <EM>terminal-type</EM> entries, or if  the  first  of  the  other  <EM>terminal-type</EM>
       entries  that  has  this  capability  gives  a  different value for the
       capability than that in the first <EM>terminal-type</EM>.

       The order of the other <EM>terminal-type</EM> entries is significant.  Since the
       terminfo  compiler  <STRONG>tic</STRONG>  does a left-to-right scan of the capabilities,
       specifying two <STRONG>use=</STRONG> entries that contain differing entries for the same
       capabilities will produce different results depending on the order that
       the entries are given in.  <STRONG>infocmp</STRONG> will flag any  such  inconsistencies
       between the other <EM>terminal-type</EM> entries as they are found.

       Alternatively, specifying a capability <EM>after</EM> a <STRONG>use=</STRONG> entry that contains
       that capability will cause the  second  specification  to  be  ignored.
       Using  <STRONG>infocmp</STRONG>  to recreate a description can be a useful check to make
       sure that everything was specified correctly  in  the  original  source
       description.

       Another  error  that  does not cause incorrect compiled files, but will
       slow down the compilation time, is specifying extra  <STRONG>use=</STRONG>  fields  that
       are superfluous.  <STRONG>infocmp</STRONG> will flag any other <EM>terminal-type</EM> <EM>use=</EM> fields
       that were not needed.

   <STRONG>Changing</STRONG> <STRONG>Databases</STRONG> <STRONG>[-A</STRONG> <EM>directory</EM><STRONG>]</STRONG> <STRONG>[-B</STRONG> <EM>directory</EM><STRONG>]</STRONG>
       Like  other  <EM>ncurses</EM>  utilities,  <STRONG>infocmp</STRONG>  looks   for   the   terminal
       descriptions   in  several  places.   You  can  use  the  <EM>TERMINFO</EM>  and
       <EM>TERMINFO</EM><STRONG>_</STRONG><EM>DIRS</EM> environment variables to override the compiled-in default
       list  of  places  to  search.   See <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>, as well as the <EM>Fetching</EM>
       <EM>Compiled</EM> <EM>Descriptions</EM> section in <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>.

       You can also use the options <STRONG>-A</STRONG> and <STRONG>-B</STRONG> to override the list  of  places
       to search when comparing terminal descriptions:

       <STRONG>o</STRONG>   The <STRONG>-A</STRONG> option sets the location for the first <EM>terminal-type</EM>

       <STRONG>o</STRONG>   The <STRONG>-B</STRONG> option sets the location for the other <EM>terminal-types</EM>.

       Using  these  options,  it  is  possible  to compare descriptions for a
       terminal with the same name located in two  different  databases.   For
       instance,  you  can use this feature for comparing descriptions for the
       same terminal created by different people.


</PRE><H3><a name="h3-Other-Options">Other Options</a></H3><PRE>
       <STRONG>-0</STRONG>   causes the fields to be printed on one line, without wrapping.

       <STRONG>-1</STRONG>   causes the fields to be printed out one to a line.  Otherwise, the
            fields  will be printed several to a line to a maximum width of 60
            characters.

       <STRONG>-a</STRONG>   tells <STRONG>infocmp</STRONG> to retain  commented-out  capabilities  rather  than
            discarding  them.   Capabilities  are  commented by prefixing them
            with a period.

       <STRONG>-D</STRONG>   tells <STRONG>infocmp</STRONG> to print the database locations that it knows about,
            and exit.

       <STRONG>-E</STRONG>   Dump  the  capabilities of the given terminal as tables, needed in
            the  C  initializer  for  a  TERMTYPE  structure   (the   terminal
            capability  structure in the <STRONG>&lt;term.h&gt;</STRONG>).  This option is useful for
            preparing versions of the curses library  hardwired  for  a  given
            terminal  type.  The tables are all declared static, and are named
            according to the type and the name of the  corresponding  terminal
            entry.

            Before  <EM>ncurses</EM>  5.0,  the split between the <STRONG>-e</STRONG> and <STRONG>-E</STRONG> options was
            not needed; but support for extended  names  required  making  the
            arrays   of  terminal  capabilities  separate  from  the  TERMTYPE
            structure.

       <STRONG>-e</STRONG>   Dump the capabilities of the given terminal as a C initializer for
            a  TERMTYPE  structure  (the  terminal capability structure in the
            <STRONG>&lt;term.h&gt;</STRONG>).  This option is useful for preparing  versions  of  the
            curses library hardwired for a given terminal type.

       <STRONG>-F</STRONG>   compare terminfo files.  This assumes that two following arguments
            are filenames.   The  files  are  searched  for  pairwise  matches
            between  entries,  with  two entries considered to match if any of
            their names do.  The  report  printed  to  standard  output  lists
            entries  with  no matches in the other file, and entries with more
            than one match.  For entries with exactly one match it includes  a
            difference  report.  Normally, to reduce the volume of the report,
            use references are not resolved before  looking  for  differences,
            but resolution can be forced by also specifying <STRONG>-r</STRONG>.

       <STRONG>-f</STRONG>   Display  complex terminfo strings which contain if/then/else/endif
            expressions indented for readability.

       <STRONG>-G</STRONG>   Display constant  literals  in  decimal  form  rather  than  their
            character equivalents.

       <STRONG>-g</STRONG>   Display  constant  character  literals  in quoted form rather than
            their decimal equivalents.

       <STRONG>-i</STRONG>   Analyze the initialization (<STRONG>is1</STRONG>, <STRONG>is2</STRONG>, <STRONG>is3</STRONG>), and reset  (<STRONG>rs1</STRONG>,  <STRONG>rs2</STRONG>,
            <STRONG>rs3</STRONG>),   strings   in   the  entry,  as  well  as  those  used  for
            starting/stopping cursor-positioning mode (<STRONG>smcup</STRONG>, <STRONG>rmcup</STRONG>)  as  well
            as starting/stopping keymap mode (<STRONG>smkx</STRONG>, <STRONG>rmkx</STRONG>).

            For  each  string,  the  code  tries to analyze it into actions in
            terms of the other capabilities in the  entry,  certain  X3.64/ISO
            6429/ECMA-48 capabilities, and certain DEC VT-series private modes
            (the set of recognized special sequences  has  been  selected  for
            completeness  over  the  existing terminfo database).  Each report
            line consists of the capability name,  followed  by  a  colon  and
            space,  followed by a printable expansion of the capability string
            with  sections  matching  recognized   actions   translated   into
            {}-bracketed descriptions.

            Here is a list of the DEC/ANSI special sequences recognized:

                      Action        Meaning
                      -----------------------------------------
                      RIS           full reset

                      RC            restore cursor
                      LL            home-down
                      RSR           reset scroll region

       It also recognizes a SGR action corresponding to ANSI/ISO 6429/ECMA Set
       Graphics Rendition, with the values NORMAL, BOLD, UNDERLINE, BLINK, and
       REVERSE.  All but NORMAL may be prefixed with

              <STRONG>o</STRONG>   "+" (turn on) or

              <STRONG>o</STRONG>   "-" (turn off).

              An  SGR0  designates  an empty highlight sequence (equivalent to
              {SGR:NORMAL}).

       <STRONG>-l</STRONG>   Set output format to terminfo.

       <STRONG>-p</STRONG>   Ignore padding specifications when comparing strings.

       <STRONG>-Q</STRONG> <EM>n</EM> Rather than show source  in  terminfo  (text)  format,  print  the
            compiled  (binary) format in hexadecimal or base64 form, depending
            on the option's value:

               1  hexadecimal

               2  base64

               3  hexadecimal and base64

            For example, this prints the compiled terminfo value as  a  string
            which could be assigned to the <EM>TERMINFO</EM> environment variable:

                infocmp -0 -q -Q2

       <STRONG>-q</STRONG>   This makes the output a little shorter:

            <STRONG>o</STRONG>   Make  the  comparison listing shorter by omitting subheadings,
                and using "-" for absent capabilities, "@" for canceled rather
                than "NULL".

            <STRONG>o</STRONG>   However,   show   differences   between  absent  and  canceled
                capabilities.

            <STRONG>o</STRONG>   Omit the "Reconstructed from" comment for source listings.

       <STRONG>-R</STRONG><EM>subset</EM>
            Restrict output to a given subset.  This option is  for  use  with
            archaic  versions of terminfo like those on SVr1, Ultrix, or HP-UX
            that do not support the full set of SVR4/XSI Curses terminfo;  and
            variants  such  as AIX that have their own extensions incompatible
            with SVr4/XSI.

            <STRONG>o</STRONG>   Available terminfo subsets are  "SVr1",  "Ultrix",  "HP",  and
                "AIX"; see <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG> for details.

            <STRONG>o</STRONG>   You  can  also  choose  the  subset  "BSD"  which selects only
                capabilities with termcap equivalents recognized by 4.4BSD.

            <STRONG>o</STRONG>   If you select any other value for <STRONG>-R</STRONG>, it is  the  same  as  no
                subset, i.e., all capabilities are used.

            A  few  options  override the subset selected with <STRONG>-R</STRONG>, if they are
            processed later in the command parameters:

            <STRONG>-C</STRONG>   sets the "BSD" subset as a side-effect.

            <STRONG>-I</STRONG>   sets the subset to all capabilities.

            <STRONG>-r</STRONG>   sets the subset to all capabilities.

       <STRONG>-s</STRONG> <EM>[d|i|l|c]</EM>
            The <STRONG>-s</STRONG> option sorts the fields within each type according  to  the
            argument below:

            <STRONG>d</STRONG>    leave  fields  in  the  order  that  they  are  stored in the
                 <EM>terminfo</EM> database.

            <STRONG>i</STRONG>    sort by <EM>terminfo</EM> name.

            <STRONG>l</STRONG>    sort by the long C variable name.

            <STRONG>c</STRONG>    sort by the <EM>termcap</EM> name.

            If the <STRONG>-s</STRONG> option is not given, the  fields  printed  out  will  be
            sorted  alphabetically  by  the  <STRONG>terminfo</STRONG>  name  within each type,
            except in the case of the <STRONG>-C</STRONG> or the <STRONG>-L</STRONG> options,  which  cause  the
            sorting  to  be  done  by  the <STRONG>termcap</STRONG> name or the long C variable
            name, respectively.

       <STRONG>-T</STRONG>   eliminates size-restrictions  on  the  generated  text.   This  is
            mainly  useful  for  testing  and  analysis,  since  the  compiled
            descriptions  are  limited  (e.g.,  1023  for  termcap,  4096  for
            terminfo).

       <STRONG>-t</STRONG>   tells  <STRONG>tic</STRONG>  to  discard commented-out capabilities.  Normally when
            translating from terminfo to termcap, untranslatable  capabilities
            are commented-out.

       <STRONG>-U</STRONG>   tells  <STRONG>infocmp</STRONG>  to  not  post-process  the  data after parsing the
            source  file.   This  feature  helps  when  comparing  the  actual
            contents  of  two  source  files, since it excludes the inferences
            that <STRONG>infocmp</STRONG> makes to fill in missing data.

       <STRONG>-V</STRONG>   reports the version of <EM>ncurses</EM> which was used in this program, and
            exits.

       <STRONG>-v</STRONG> <EM>n</EM> prints  out  tracing  information on standard error as the program
            runs.

            The optional parameter <EM>n</EM> is a number  from  1  to  10,  inclusive,
            indicating the desired level of detail of information.  If <EM>ncurses</EM>
            is built  without  tracing  support,  the  optional  parameter  is
            ignored.

       <STRONG>-W</STRONG>   By  itself,  the  <STRONG>-w</STRONG>  option  will  not  force  long strings to be
            wrapped.  Use the <STRONG>-W</STRONG> option to do this.

       <STRONG>-w</STRONG> <EM>width</EM>
            changes the output to <EM>width</EM> characters.

       <STRONG>-x</STRONG>   print information for user-defined capabilities (see <STRONG><A HREF="user_caps.5.html">user_caps(5)</A></STRONG>.
            These  are  extensions  to  the  terminfo  repertoire which can be
            loaded using the <STRONG>-x</STRONG> option of <STRONG>tic</STRONG>.

       X/Open  Curses  Issue 7  (2009) specifies <EM>infocmp</EM>.  It does not mention
       options for producing descriptions in <EM>termcap</EM> format.

       SVr4  <EM>infocmp</EM>  does  not  distinguish  between  absent   and   canceled
       capabilities.   It  furthermore reports missing integer capabilities as
       <STRONG>-1</STRONG> (its internal representation).  <EM>ncurses</EM> shows these  as  "NULL"  for
       consistency with missing string capabilities.

       The  <STRONG>-r</STRONG>  option  of  <EM>ncurses</EM>  <EM>infocmp</EM>  uses  SVr4's notion of "termcap"
       capabilities.  BSD <EM>curses</EM> had a more restricted set.  To see only those
       present in 4.4BSD, use "<STRONG>-r</STRONG> <STRONG>-RBSD</STRONG>".

       Although  System  V  Release  2  provided a terminfo library, it had no
       documented tool for decompiling the terminal descriptions.  Tony Hansen
       (AT&amp;T) wrote the first <STRONG>infocmp</STRONG> in early 1984, for System V Release 3.

       Eric  Raymond  used  the  AT&amp;T  documentation  in  1995  to  provide an
       equivalent <STRONG>infocmp</STRONG> for <EM>ncurses</EM>.   In  addition,  he  added  a  few  new
       features such as:

       <STRONG>o</STRONG>   the   <STRONG>-e</STRONG>   option,   to  support  <EM>fallback</EM>  (compiled-in)  terminal
           descriptions

       <STRONG>o</STRONG>   the <STRONG>-i</STRONG> option, to help with analysis

       Later, Thomas Dickey added the <STRONG>-x</STRONG> (user-defined  capabilities)  option,
       and  the  <STRONG>-E</STRONG>  option  to  support  fallback  entries  with user-defined
       capabilities.

       For a complete list, see the <EM>EXTENSIONS</EM> section.

       In 2010, Roy Marples provided an <STRONG>infocmp</STRONG> program  for  NetBSD.   It  is
       less  capable  than  the  SVr4  or <EM>ncurses</EM> versions (e.g., it lacks the
       sorting options documented in X/Open), but does include the  <STRONG>-x</STRONG>  option
       adapted from <EM>ncurses</EM>.
